/**
 * An abstract class that creates the glue necessary to implement peering
 * between Java objects and native C structures.
 *
 * In this implementation, peering is done by keeping the memory address of
 * a C data structure in a private object field.  The field is a long, to
 * ensure that we can store both 32-bit and 64-bit addresses.
 *
 * This field should never be accessed from Java.  Only native C code from
 * mod_java should use this field.
